Abstract :
Amongst all of the construction substances which are available for construction, we understand that concrete is
an extensively used creation fabric for building of various civil engineering structures. Concrete will supply higher durability
and also its costs during production in addition to maintenance are very low when in comparison to different production
substances. So that it will maintain its properly filling capacity, non-block glide and homogeneity. as a consequence, restrict
high cement content which could raise cost as well as cause temperature increase throughout hydration and probably affect
other traits like creep and shrinkage, subsequently giant quantities of additives are typically Metakaolin as a partial
replacement for cement in concrete, aiming to enhance housing quality and reduce heat generation. Various admixtures are
known to improve concrete’s strength and workability, with Metakaolin standing out due to its distinct advantages. It
significantly improves durability and resistance against chloride and sulphate attacks, freezing-thawing cycles, alkali-silica
reactions, and frost damage. Additionally, Metakaolin enhances compressive strength, reduces permeability and bleeding,
and strengthens the interfacial transition zone (ITZ), eliminating its typical weaknesses. In this research, concrete mixes
incorporating 5%, 10%, 15%, and 20% Metakaolin were evaluated to determine optimal performance. At the optimal level
of 15% Metakaolin, further cement replacement was done using fly ash at 10%, 20%, and 30% by weight. The hardened
properties of these mixes were tested for compressive strength at 7, 28, 56, and 90 days, while split tensile and flexural
strength were measured at 28 days.
